Presideni's budget would cut Interior by $1.5 billion, or 12%

 Here's a quick summary from the President's proposed budget:

The Department of the Interior (DOI) is responsible for protecting and managing vast

areas of U.S. lands and waters, providing scientific and other information about its natural resources, and meeting the Nation’s trust responsibilities and other ommitments to American Indians, Alaska Natives, and U.S.-affiliated island communities. The Budget requests an increase in funding for core energy development programs while supporting DOI’s priority agency mission and trust responsibilities, including public safety, land conservation and revenue management. It eliminates funding for unnecessary or duplicative programs while reducing funds for lower priority activities, such as acquiring new lands. The President’s 2018 Budget requests $11.6 billion for DOI, a $1.5 billion or 12 percent decrease from the 2017 annualized CR level.

I'll have more analysis and figures as time allows...
